An upstream change broke our build scripts in a very confusing way.

I think KBUILD_EXTRA_SYMBOLS was added in 2.6.26.
Since we no longer need to build on anything older than 2.6.32
I can use that instead of copying the Module.symvers from the
other build directory and relying on the build scripts passing
-I Module.symver to modpost.

I just need to find a suitable system to check it on.
All made more difficult by working from home....
